FREDERICK C. KERRY, OF DETROIT, MICHIGAN;

INTERCHANGEABLE REACH AND SHORT-TURNING GEAR.

SPECIFICATION forming part of Letters Patent No. 736,738, dated August18, 1903.

Application filed November 3, 1902. Serial N6." 129,976. (No modeL) Toall whom it may concern:

Be it known that I, FREDERICK C. KERBY, a subject of the King ofGreatBritain, residing at Detroit, countyof Wayne, State of Michigan,have invented a certain new and useful Improvement in InterchangeableBeaches and Short-Turning Gears for Wagons; and I declare the followingto be a full, clear, and exact description of the invention, such aswillenable others skilled in the art to which it pertains to make and usethe'same, reference being had to the accompanying drawings, which form apart of thisspecification.

This invention relates to an interchangeable reach and short turninggearfor wagons, and has for its object an improved means for connectingthe front and rear axles of a wagon by means of which the connection maybe used interchangeably as an ordinary reach or as a short-turning gear.

In the drawings, Figure 1 is a plan View showing the invention. Fig. 2is a side ele vation. Fig. 3 shows the two reaches brought to theposition of an ordinary gear of a wagon.

A indicates the front axle, and B the rear axle. A reach 0 is pivotallyheld by kingbolts 1 and 2 to both axles. In addition to this reach 0,which determines the spread of the axles and which is used for draftpurposes, there is rigidly secured to the rear axle a tongue 3,extending forward from the fixed hounds at, and there is pivotallysecured to the front axle a tongue 5, extending rearwardly from thefront axle A, pivotally secured to the front axle by the king-bolt 1 andengaging between the cross-bars6 and 7, that join the rear ends of thefront hounds. The tongue 5 is provided with a bolt-hole through which abolt 8 engages and secures the tongue 5 rigidly with respect to thefront hounds. One of the tongues 3 or 5 is forked, asshown in thedrawings. The rear tongue 3 is forked, and the end of the tongue 5engages between the branches 3-and' 3 of" the fork. Both forks 3 and 3of the tongue 3 are provided with slots extending longitudinally of theaxis of the tongue 3, and the tongue 5 is provided with a slot, and theslots 16 through the forks of the tongue 3, and 9 through the tongue 5,register, and the tongues are held together by a bolt 10, which passesthrough a friction-roller 11, nearly filling, but slightly less indiameter than, the cross-distance between the sides of the slot. Theroller is held from escaping by washers 12 and 13. The tongue 5 isprovided'near its end with a bolt- 1 hole 14, and the tongue 3 isprovided with a bolt-hole 15, properly spaced to register with bolt-hole14 when the two parts of the pivoted reach are brought to a positionparallel with the integral reach 0.

When it is desired to use the device as a short-turning gear, it isassembled as shown in Fig. 1, in which case the hind wheels are guidedto track in the curve traversed by the front wheel.

When it is desired to use the invention for an ordinary reach, the pin 8is removed and the parts of the pivoted reach and the integral reach arebrought to a parallel position and the pin is dropped through the holes14. and 15. This couples the pivoted reach and makes it a substantiallyunpivoted or integral reach, and its operation is similar to that of theordinary reach, which remains at all times parallel with the integralreach G.

What I claim is- 1. In an interchangeable ordinary reach andshort-turning gear, the combination of the rear cross-bar of the fronthounds slotted the whole of their length, provided with a removable pin8, in combination with overlapping tongues 3 and 5, one of saidoverlapping tongues being forked, and both being slotted, a roller 10engaging through the slots of both said tongues, and the reach 0arranged as described and for the purposes specified.

2. The rear cross-bar of the front hounds slotted throughout its lengthprovided with a removable pin 8, in combination with the pivoted reachcomposed of overlapping tongues 3 and 5, both of said tongues beingslotted and one of said tongues being forked to receive the overlappingpart of the other tongue, the roller 10 passing through the slotted forkand through the slot of the tongue 5, and arranged to form an adjustable frictionless connection, and the reach 0 pivotally secured toboth axles, the tongues 3 and 5 being provided with bolt-holes 14c and15, whereby the reach may be changed from a short-turning gear to anordinary reach, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

FREDERICK O. KERBY.
